-Static providers
-----------------
-
-.. currentmodule:: dependency_injector.providers
-
-Static providers are family of providers that return their values "as is".
-There are four types of static providers:
-
-    - :py:class:`Class`
-    - :py:class:`Object`
-    - :py:class:`Function`
-    - :py:class:`Value`
-
-All of them have the same behaviour (inherited from 
-:py:class:`StaticProvider`), but usage of any is predicted by readability 
-and providing object's type.
-
-Example:
-
-.. literalinclude:: ../../examples/providers/static.py
-   :language: python
-   :linenos:
